DESCRIPTION:'Planetary atmospheres record a plethora of processes dating f
 rom accretion\, early bombardment\, and subsequent volcanic growth.  Wheth
 er for solar system planets or exoplanets\, the present-day composition of
  atmospheres is a rich archive of information on their geological history.
   In the case of warm rocky planets their atmospheres may constrain the in
 terior composition and dynamics of the planet\, offering exciting potentia
 l to understand exoplanet interiors.  \n\n'In this talk I present our rece
 nt results investigating the role of early massive impacts and volcanic de
 gassing in building planetary atmospheres on rocky planets.  These results
  show the prospects and limitations of having to view planetary processes 
 through the lens of their atmospheres.  I also discuss how Venus provides 
 a key solar system analogue to warm rocky exoplanets\, the chemistry of wh
 ich provides a reference case for predictions of atmospheric chemistry on 
 Venus-like exoplanets.'
